My car read .675 and obviously when I moved the throttle reel, the throttle motor will move the TPS and the voltage will raise. ... All you need from the tools is a multimeter. I loosened the TPS and moved it until the voltage was 0.99-1.00V on my multimeter and then tightened the screws back down. Open and close the throttle a few times to check the idle setting is stable and adjust if required. Slapped the multimeter on the terminals and received a reading of 794Ω as below. When installing and adjusting the TPS, some tips: 1. This causes your throttle position sensor to adjust the engine intake manifold accordingly. WOT setting is more important than idle. What you will need: 1. Either my multimeter is off, or there's some additional resistance in there. A pin or needle (mine have alligator clips attached to them) C. I fired it up basically cold and the idle was much better and smoother than before but seemed like it was just a tad too fast. Volume controls, tone controls, and balance controls are all three-terminal potentiometers. RESISTANCE TEST: is only to test the tps. Here are the contents of this tutorial at a glance: Symptoms of a Bad Throttle Position Sensor (TPS). if you quickly open the throttle fully) the voltage value should quickly change to 4.5+v and then settle … Reconnect temp sensor. go back to the engine bay and loosen the two philip screws that hold the TPS on the throttle body then and tighten until snugish, turn the TPS left to right while waching the multimeter you want it to be .50v. Still, I now have some reference figures.) If the throttle position sensor test does not reach 5 volts, this is a sign that the throttle position sensor needs to be replaced. To check and adjust the TPS you'll need a digital multimeter, two small straight pins, and a screw driver. Adjust it until its at .65 volts on the multimeter. This vital sensor allows your engine to maintain a proper amount of air. To make your voltage adjustment, loosen 2 small screws that hold clamps that hold the tps. A modern car consists of many components and assemblies. To adjust the TPS all you have to do is loosen (don't take them out) both screws and move the TPS until you see the right voltage. To adjust the Throttle Position Sensor you will require a T-25H Security Torx bit to undo the two bolts that hold it in place on the right side of the rear Carburettor and a Multimeter to measure the … The FSM requires an OBDII to check current data of the throttle position while adjusting … How to Adjust the Throttle Position Sensor Before adjusting the TPS make sure that you do a carb sync and set the idle speed beforehand as this could effect the reading. 6. Carefully tighten the screws to 31 In.Lbs. Here's a brief tutorial on my method of adjusting the APS (accelerator position sensor) on a Kia Forte. Using the TPS test tool, verify the TPS is set to 0.70 +/- 0.01 Vdc. If you adjusted the throttle linkage rod (6), set it back to its approximate original position. The TPS is now set and the horizontal throttle body stop screw (7) should not be touched again. This feature is dependent on the throttle valve. The TPS set up routine reads the mv value of the TPS with the throttle closed and stores this value in the ECU as the baseline for the fuelling. Tighten 2 screws. 306 GTI-6 TPS (Throttle Position Sensor) Testing With A Multimeter The TPS on a Peugeot 306 GTi-6 is located under the throttle body and can be easily accessed by … Gently! TEST 1: Testing the Throttle Position Sensor Voltage Signal. I couldn't get the idle under 1400 until I took the TPS off and turned the "double smile" so that it would catch the butterfly lever while it was completely closed. As you open the throttle plate, the digital multimeter should increase to 5 volts. To hook the multimeter up you will have to pierce the green wire (red arrows) with a pin so you can check how much voltage is going through it. The voltage should fluctuate between 0.1 and 5v depending on the engine load. This is a very touchy adjustment and your reading will likely change slightly when you tighten the screws back up, you need to compensate for this change when adjusting, it needs to be .700 when tight. So, turn on the ignition and look at … ... You can adjust the position of the TPS with a multimeter but you need to know what value is stored in the ECU to set it up correctly. 7mm socket with extension and a lot of patience. If you have a logger that will show the actual value of the idle position switch then you can use it to replace the multimeter for measuring continuity. (3.5 Nm) when the voltage is 0.70 +/- 0.01 Vdc. I went out to the shed after reading your post on the TPS adjustment. Wait a minute for the engine idle to level off, then use a pen and paper to write down the RPMs that your engine settles and idles at. First set airbypass screws to 0 by screwing all the way in. I then was able to reset it to approx. You either have to get k-pro, or spend $20 and buy a multimeter. The manual has you place a 0.0177" (0.45mm) feeler guage between the stop screw and the throttle pulley to open the butterfly and then adjust the TPS right to where the IPS (pins 3 and 4) switches from closed … If it is set too high, it will have a hard time detecting the voltage of a weaker current. TPS Adjust (mechanical) Engine off. 2G's critical adjustment is the Idle Position Switch that's part of the TPS. TPS is a fancy new name for the old three-terminal potentiometer that is commonly known by many different names. To test this sharply open the throttle and watch for the voltage change, under high vacuum (e.g. You may need to let the engine run for a few minutes in order for it to come down to its normal idle speed. If the digital multimeter reads between .2 to 1.5 volts, then the throttle position sensor is working correctly. Throttle position sensor. The FSM procedure is to set where the IPS opens and closed in relation to throttle shaft opening. Rotate tps slightly until you can get your settings. The contents of this tutorial at a glance: Symptoms of a Bad Throttle Position Sensor. To test the TPS you don't need a scan tool (although having one is major plus). If the multimeter displays a negative number, for example, the probes are most likely in the wrong place. Now turn on your multimeter and set it to volts (DC), connect it to terminals 1 & 2 and start the engine. Picture 2 To hook the multimeter up you will have to pierce the green wire with a pin so you can check how much voltage is going through it. (Yes, and I know this doesn't add up to 5080 in both cases. To adjust the TPS base-line, slightly loosen the screws, then slowly turn the TPS clockwise or counter-clockwise to adjust the voltage. Let's take a look at what your test results mean: CASE 1: The multimeter registered 4.5 to 5 Volts.This is the correct test result and confirms that the fuel injection computer and the circuit is supplying the TPS with power.
